Your lava lesson for the day:
UL - Igneous rock, likely formed from cooled and solidified lava.
The rough, textured appearance and dark coloration are characteristic of volcanic rock formations, such as basalt.

UR - Basalt is characterized by:
Composition: It is a dark, fine-grained igneous rock primarily composed of plagioclase feldspar, pyroxene, and often olivine.
Formation: It forms from the rapid cooling of basaltic lava, often associated with volcanic eruptions and making up much of the ocean floor.

LR - classic example of Pahoehoe (pronounced pah-hoy-hoy) lava. This type of basaltic lava is known for its smooth, billowy, or rope-like surface.

LL - Basalt is characterized by:
Composition: It is a dark, fine-grained igneous rock primarily composed of plagioclase feldspar, pyroxene, and often olivine.
Formation: It forms from the rapid cooling of basaltic lava, often associated with volcanic eruptions and making up much of the ocean floor.
